2 INTRODUCTION Public Stakeholder Meeting Order 890 Objective to improve transparency and stakeholder involvement. Planning Process Defined in Attachment K of OATT March Meeting Reviewed Planning Process Coordination with WECC (PCC & TEPPC), WestConnect PNM 10-Year Plan Study Scope November Meeting Review 10-Year Plan Results Input to Next Planning Cycle Certain Other Business 2

3 10-YEAR TRANSMISSION PLAN 3

4 10-YEAR TRANSMISSION PLAN OBJECTIVES OF STUDY EFFORT: Support Data Base Development for PNM and Regional Studies 2019 (1-yr), 2022 (5-yr), 2027 (10-yr) Maintain Reliability Define Transmission for Native, Network and Point-Point Customers Incorporate Plans Developed Through FERC Processes, NM IRP and Regional Planning Analysis 4

5 STUDY SCOPE Review transmission adequacy with retail and network customer updates to designated network resources and load. Determine if system mitigations are needed to serve expected obligations (load forecasts and expected firm transfers) during the 10 year planning horizon without violating WECC/NERC reliability standards. Develop operational mitigations or system improvements to maintain system reliability and associated cost estimates and schedule. Incorporate assessments of economic congestion to the extent a need is identified by PNM s or other s involvement in the WECC process for providing this type of assessment. 5
